I've been running into a few problems with regular expressions in D. One of the issues I've had recently is matching strings with non ascii characters. As an example:
auto re = regex( `(.*)\.txt`, "i" ); re.printProgram(); auto m = match( "bà.txt", re ); writefln( "'%s'", m.captures[1] ); When I run this I get the following error: dchar decode(in char[], ref size_t): Invalid UTF-8 sequence [160 46 116 120] around index 0 printProgram() 0: REparen len=1 n=0, pc=>10 9: REanystar 10: REistring x4, '.txt' 19: REend While investigating the cause, I noticed that during execution of many of the regex instructions (e.g. REanystar), the source is advanced with: src++; However in other cases (REanychar), it is advanced with: src += std.utf.stride(input, src); I found that by replacing the code REanystar with stride, the code worked as expected. Although I can't claim to have a solid understanding of the code, it seems to me that most of the cases of src++ should be using stride instead. Is this correct, or have I made some silly mistake and got completely the wrong end of the stick?
